Resonant optical trapping of Janus nanoparticles in plasmonic nanoaperture
Alemayehu Nana Koya, Longnan Li, Wei Li
Controlled trapping of light absorbing nanoparticles with low-power optical tweezers is crucial for remote manipulation of small objects. This study takes advantage of the synerget…
Multifunctional Charge Transfer Plasmon Sensors
Alemayehu Nana Koya, Wei Li
Charge transfer plasmon (CTP) modes arise when metallic nanoparticles are connected by a conductive junction. These ultatunable plasmonic modes can be actively tuned and broadly mo…
Integrated Metasurface-based Wavelengths Division Demultiplexers
Amged Alquliah, Mohamed ElKabbash, JinLuo Cheng +2
We present a design approach for realizing on-chip wavelength division demultiplexing (WDD) schemes by integrating all-dielectric metasurfaces of TiO2 nanorod arrays into a SiN wav…
Difficulties of the traditional PhC-based superprisms
Wei Li, Xiaogang Zhang, Xulin Lin +1
This paper is to discuss the difficulties of the traditional photonic crystals (PhC) -based superprisms.
Visually moving objects to an arbitrary distance by a simple shifting cloak
Jianguo Guan, Wei Li, Zhigang Sun +1
A rectangular "shifting cloak", which visually shifts the cloaked object for a certain distance from the original place, is proposed. Comparing with the previously proposed similar…
